Orbital evolution of P\v{r}\'{i}bram and Neuschwanstein

TL;DR

This study investigates the orbital history of meteorites Příbram and Neuschwanstein over 5000 years, finding their orbits remained similar and identifying a few celestial objects with comparable orbital evolution.

Contribution

The paper provides a detailed orbital analysis of Příbram and Neuschwanstein, including clone simulations and searches for similar objects, revealing rare orbital similarities over millennia.

Findings

Meteorites maintained similar orbits over 5000 years.

Few meteors and asteroids show similar orbital evolution in the last 2000 years.

Identified objects with comparable orbital paths to the meteorites.

Abstract

The orbital evolution of the two meteorites P\v{r}\'{i}bram and Neuschwanstein on almost identical orbits and also several thousand clones were studied in the framework of the N-body problem for 5000 years into the past. The meteorites moved on very similar orbits during the whole investigated interval. We have also searched for photographic meteors and asteroids moving on similar orbits. There were 5 meteors found in the IAU MDC database and 6 NEAs with currently similar orbits to P\v{r}\'{i}bram and Neuschwanstein. However, only one meteor 161E1 and one asteroid 2002 QG46 had a similar orbital evolution over the last 2000 years.
